So you’re applying ED and you know it’s a reach. So why stress.
Like everyone, have targets and safeties as well.
No reason to stress. Your grades and test are what they are. Keep studying - and everything will turn out well.
What excites you about Va Tech? Is it the location or the major?
Other schools, such as TN Tech, offer the major but you can probably find something similar at other schools. What other schools are you looking at? Obviously in-state you have Illinois State and the directionals such as Southern Illinois. And there’s lots of great out of state schools that will work.
I hope Va Tech works but I think it’s a reach. But no reason to stress - there’s tons of great schools out there for you.
Control what you can. And don’t fall in love with any one school because there’s many that will work for you.
Good luck.
